BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to a piece of furniture, with a furniture carcasswhich comprises two carcass side walls which lie opposite one another,and with at least one pair of guide units for guiding a movablefurniture part, in particular drawer, in the furniture carcass, whereinthe carcass side walls each comprise at least one assembly interfacewhich comprises at least two fastening holes which are arranged behindone another in a side wall depth direction and at which the guide unitsof the pair are fastened lying opposite one another.

Description of Related Art

Such furniture has been known for some time. Each household has severalsuch pieces of furniture, with furniture carcasses in which drawers aremovable guided. The drawers are guided by way of guide units, of whichone guide unit is fastened to the left side wall and another guide unitoppositely to the right side wall of the furniture carcass. Thefurniture carcasses can consist of wood or metal. Since drawers have asignificantly weight, in particular in the loaded state, the fasteningof the associated guide units on the side walls must also be designedsuch that the weight of the drawer is reliably accommodated. Thisdemands an adequate stability on the part of the side walls of thefurniture carcass, so that for example thin plywood plates are notsuitable for such side walls.

Side walls of furniture carcasses which are known from the state of theart therefore have a relatively large wall thickness and are relativelyweighty, by which means a relatively large amount of construction spaceis taken up. This too is not particularly aesthetically pleasing.

SUMMARY OF THE INVENTION

It is therefore the object of the invention to provide a piece offurniture of the initially mentioned type which compared to furniturefrom the state of the art as a whole takes up less construction spaceand is designed in an aesthetically pleasing manner, in particular withregard to the design of the side walls.

This object is achieved by a piece of furniture with the features andaspects discussed below.

The piece of furniture according to one non-limiting embodiment of theinvention is characterised in that the carcass side walls, forincreasing their stiffness, each comprise at least two embossings whichare arranged above one another in a side wall height direction, whereinthe embossings are designed in a raised manner on the inner side of therespective carcass side wall and wherein at least one assembly interfaceis arranged between two adjacent embossings in the side wall heightdirection.

The embossings ensure an increase in the stiffness of the side walls, sothat their wall thickness can turn out to be significantly smaller thanwith the state of the art, but despite this a reliable fastening of theguide units to the side wall is possible. A finished carcass with sidewalls which are designed in such a manner has a lower weight whencompared to conventional finished carcasses. Furthermore, the side wallswith a lower wall thickness have a significant influence on theaesthetics. One aspect which must not be neglected is further the factthat the assembly interfaces for the connection of the guide units arearranged between adjacent embossings in the side wall height direction.The clear width of the furniture carcass which is available for theassembly of the guide units is therefore not comprised by theembossings. In contrast, compared to conventional furniture carcasseswith relatively broad side walls, with this solution a movable furniturepart, in particular a drawer, can be used with a greater width and hencein the case of a drawer with a larger storage space.

Concerning a further development of the invention, the fastening holesof the assembly interfaces are configured for the tool-free assembly ofthe guide units on the carcass side walls. For example, it is possiblefor the fastening holes to be designed in a keyhole-like manner as partof a bayonet connection. An alternative tool-free fastening can beeffected by way of a clip connection, wherein for example clip elementswhich are arranged on the guide units can be clipped into the fasteningholes.

Alternatively to the tool-free fastening of the guide units at thefastening holes of the assembly interfaces, an assembly which is nottool-free is also possible, for example by way of a screw connection.

Concerning a further development of the invention, the guide unitcomprises a carcass rail and at least one runner rail which is lineallymovably guided on the carcass rail, wherein the carcass rail is fastenedto the carcass side wall at the assigned assembly interface. The carcassrail can comprise several fastening brackets which are arranged behindone another in the rail longitudinal direction or a single continuous,long fastening bracket for its fastening to the carcass side wall in theregion of the assigned assembly interface. It is possible for severalrunner rails to be provided, of which one runner rail is a pull-out railand another rail is a middle rail. The middle rail is incorporatedbetween the carcass rail and the pull-out rail and is guided in alinearly movable manner with respect to the pull-out rail as well aswith respect to the carcass rail. The combination of the carcass rail,the middle rail and the pull-out rail is also denoted as a full pull-outor full extension.

In a particularly preferred manner, the at least one assembly interfaceis designed deepened in a channel-like manner with respect to theembossings and comprises an assembly surface which has the fasteningholes.

In a particularly preferred manner, several assembly interfaces areprovided, these each being arranged between two embossings which arearranged adjacently in the side wall height direction. It is alsopossible for the furniture carcass to comprise several movable furnitureparts which lie above one another, for example drawers, which are eachfastened to the assigned carcass side walls via assembly interfaces andassociated fastening holes, wherein the assembly interfaces are eacharranged between embossings on the carcass side wall.

It is possible for the assembly interfaces which are deepened in achannel-like manner to be connected to one another at their front andrear side which lie in the side wall depth direction, in each case via avertical channel in a manner such that a ladder-like structure isformed.

Concerning a further development of the invention, the fastening holesof a respective assembly interface are arranged in several hole groupswhich each comprise several fastening holes which are arranged in acommon height plane in the side wall depth direction, wherein the holegroups are arranged above one another in the side wall height direction.The arrangement of the fastening holes in hole groups provides theadvantage that the guide unit which is to be fastened can be adjusted inthe height direction and the depth direction and pairs of fasteningholes and assembly holes which are flush with one another can always befound on sides of the guide unit even in different adjustment positions.

Concerning a further development of the invention, the carcass sidewalls are designed as sheet components, in particular as sheet metalcomponents. For example, it is possible to design the carcass side wallsas fine sheet components.

In the case of fine sheet carcass side walls, the material thickness ofsuch side walls is smaller than 3 mm, preferably 0.5 to 1.5 mm, inparticular 0.7 mm to 1 mm.

In the case of side walls which are not designed as fine sheetcomponents, the carcass side walls can have a wall thickness which liesin the range of 4 mm to 30 mm, preferably 6 mm to 19 mm, in particular 8mm to 16 mm.

In the case of carcass side walls which are designed as sheetcomponents, there results the advantage that these in comparison towooden components are significantly easier to clean and the cleaning canbe carried out with chemicals. The field of application of suchfurniture not only lies in the kitchen, but office furniture designed insuch a manner is also conceivable.

Concerning a further development of the invention, the piece offurniture comprises at least one movable furniture part, in particulardrawer, which is guided in the furniture carcass by way of a pair ofguide units. However, other movable furniture parts are alsoconceivable, for example a furniture pull-out which is not designed as adrawer, or a furniture flap.

Concerning a further development of the invention, at least one of thecarcass side walls comprises holding means for holding an electricallead. Usefully, at least one electrical lead, for example an electricitycable is held on the holding means. Alternatively or additionally, it ispossible for the carcass side walls to comprise at least one opening forleading through an electrical lead. Usefully, at least one electricallead is led through the assigned opening.

Concerning a further development of the invention, the piece offurniture comprises a base and a rear wall which are each connected tothe carcass side walls by way of fastening means, wherein preferably thefastening means are configured for a tool-free fastening of carcass sidewalls, base and rear wall to one another.

In a particularly preferred manner, the fastening means comprise clawelements which in particular are formed on the carcass side walls andwhich dig into the material, in particular wood material, of the baseand/or of the rear wall. Usefully, a furniture carcass which ismanufactured in such a manner is a hybrid component with carcass sidewalls of metal and with the base and rear wall of wood.

Concerning a further development of the invention, at least one of thecarcass side walls comprises at least one cavity, in which electricalfunction components, in particular electrical cables and/or at least oneillumination element is received for illuminating the movable furniturepart are received.

Concerning a further development of the invention, the carcass sidewalls comprise a coating for sound reduction, particularly on theirouter side.

It is possible for the carcass side walls to be screwed at the top towooden transverse profiles, preferably clipped on with a steel bracketfor a matching carcass width.

It is possible for in particular height-adjustable adjustment feet to beintegrated into the carcass side walls.

Furthermore, it is possible for the carcass side walls to each compriselatching and quick connection elements for the connection of furtherfurniture carcasses. The latching and quick connection elements can beintegrated for example into the assigned carcass side walls, preferablyare able to be clipped in as a metal and/or plastic part, or as a metaland/or plastic part are able to be screw-connected to the assignedcarcass side wall.

The piece of furniture according to another non-limiting embodiment ofthe invention is characterised in that the assembly elements eachcomprises a base section which is connected to the guide unittransversely to a longitudinal direction of the guide unit, and aplate-like assembly section which is aligned in a height direction ofthe guide unit, is connected to the base section and projectstransversely from this, the outline of said assembly section beingsmaller than the opening cross section of the assigned fastening hole ina manner such that the assembly section is stuck through the fasteninghole and is fastened to the edge which surrounds the fastening hole andis formed by the carcass side wall, by way of holding means.

Such a solution provides a tool-free fastening of the guide units to theassociated carcass side wall. Due to the fact that the assembly sectionsof the guide units are fastened to the edge of the fastening hole viaholding means, the wall thickness of the assigned carcass side wall canbe kept relatively low. At all events, a reliable holding is given bythe clamping via the holding means.

Concerning a further development of the invention, the holding meanscomprise a clamping tongue which is preferably bent out of the materialof the assembly section counter to the insertion direction and by way ofwhich the assembly section is fixedly clamped on the edge of theopening.

DESCRIPTION OF THE INVENTION

FIGS. 1 to 8 show a first embodiment example of a piece of furniture 11according to the invention. The piece of furniture can be applied as akitchen furniture in region of the kitchen or as a office furniture inan office. The piece of furniture 11 according to the invention, by wayof example comprises a movable furniture part 12 (FIG. 3) which here byway of example is represented in the form of a drawer. However, it isalso possible to apply movable furniture parts 12 other than drawers,for example furniture pull-outs which are designed in a differentmanner. Hereinafter however, the invention is to be explained by way ofexample with the application of a drawer.

The piece of furniture 11 comprises a furniture carcass 13 which in theshown example comprises two carcass side walls 14 a, 14 b which lieopposite one another. The furniture carcass 13 further comprises a base15 which in a manner which is explained hereinafter in detail isconnected to the two carcass side walls 14 a, 14 b and keeps the twocarcass side walls 14 a, 14 b at a distance to one another. At the upperside of the furniture carcass 13 which is opposite to the base 15, anupper termination is provided, said termination being shown by way ofexample in the form of two transverse profiles 16 a, 16 b which on theone hand are connected to the one and on the other hand to the othercarcass side wall 14 a, 14 b. Of course, it is also possible to usedifferently designed upper terminations of the furniture carcass 13,instead of the transverse profiles 16 a, 16 b, for example an uppercover which closes off the upper side of the furniture carcass 13 overthe complete surface. However, it is particularly with kitchen furniturethat it is often the case that such furniture is arranged below alarge-surfaced cover plate or working plate which then for its parttogether forms the upper termination of several such pieces offurniture.

In contrast, with the example of office furniture, an upper cover plateis indeed conceivable, for example for the case that the piece offurniture is a roller container which then as a furniture part which canbe handled in a unitary manner comprises such an upper cover plate.

Furthermore, the furniture carcass 13 can comprise a rear wall (notrepresented) which forms the rear termination of the piece of furniture12.

As a whole, in the shown example case, an interior 17 is defined by thetwo carcass side walls 14 a, 14 b, the base 15 and the two transverseprofiles 16 a, 16 b, in which interior several drawers are received aswill yet be explained in more detail hereinafter and are each movablyguided by way of guide units 18. In the shown example, it is for examplepossible for five drawers which lie above one another in a side wallheight direction 19 to be received in the interior 17 of the piece offurniture 11

An essential aspect of the invention is the connection of the guideunits 18 onto the assigned carcass side walls 14 a, 14 b.

For guiding a drawer, a pair of guide units 18 is provided, wherein thecarcass side walls 14 a, 14 b each comprise at least one assemblyinterface 20 a, 20 b which comprises at least two fastening holes 22which are arranged behind one another in a side wall depth direction 21and on which the guide units 18 of the pair are fastened in a mannerlying opposite one another.

In comparison to conventional furniture, the piece of furniture 11according to the invention comprises carcass side walls 14 a, 14 b witha relatively low wall thickness. This on the one hand results in aweight reduction when compared to conventional furniture and on theother hand such furniture with relatively thin-walled carcass side walls14 a, 14 b also meets the increased fashion demands as are come acrosstoday.

The reduction of the wall thickness of the carcass side walls 14 a, 14 bfor achieving the aforementioned results, in contrast does not lead tothe effect of the side walls become instable by way of this and areliable fastening of the guide units to the carcass side walls 14 a, 14b at the assembly interfaces not being possible on account of this.

Concerning the furniture according to the invention, the carcass sidewalls 14 a, 14 b each comprise at least two embossings 23 which arearranged above one another in the side wall height direction 19, forincreasing their stiffness, wherein the embossings 23 are formed in araised manner on the inner side of the respective carcass side wall 14a, 14 b and with regard to which at least one assembly interface 20 a,20 b is arranged between two adjacent embossings 23 in the side wallheight direction 19.

Due to the fact that the assembly interfaces 20 a, 20 b are arrangedbetween two embossings 23 which are adjacent in the side wall heightdirection 19, the inwardly raised embossings 23 does not restrict theconstruction space which is available for guiding the drawer.

In the shown example case, the carcass side walls 14 a, 14 b aredesigned as sheet components, in particular as sheet metal components.It is possible for example to shape the embossings 23 out of a flatlylying blank sheet part is arranged in a level manner, by way of anembossing or punching procedure. Herein, usefully all embossings areformed out by an embossing or punching procedure.

In a particularly preferred manner, sheet metal components of finesheet, in particular fine sheet steel are provided as carcass side walls14 a, 14 b. The wall thickness of such fine sheet carcass side walls isless than 3 mm, preferably 0.5 mm to 1.5 mm, in particular 0.7 mm to 1mm.

As is particularly shown in FIG. 1, the assembly interfaces 20 a, 20 bare designed deepened in a channel-like manner with respect to theembossings 23 and have an assembly surface 25 which comprises thefastening holes 22. The assembly interfaces 20 a, 20 b which aredeepened in a channel-like manner are connected to one another at theirfront side 26 and rear side 27 which lie in the side wall depthdirection, via a vertical channel 28, in a manner such that aladder-like structure is formed.

In the shown example, the assembly interfaces 20 a, 20 b at their frontside 26 are lengthened beyond the vertical channel by way of a channelsection 29 which is relatively short in the side wall depth directionand which runs out at the front edge of the carcass side walls 14 a, 14b.

As already mentioned, the guide units 18 for guiding the drawer arefastened at the assembly interfaces 20 a, 20 b. As is particularly shownby way of example in FIG. 3, the piece of furniture is equipped withthree drawers which are arranged above one another in the side wallheight direction 19, wherein three pairs of guide units are provided, ofwhich a pair serves for guiding a drawer. The guide units 18 of a pairare fastened to assembly interfaces 20 a, 20 b of the one and of theother carcass side wall 14 a, 14 b, said interfaces lying opposite oneanother. The associated assembly interfaces 20 a, 20 b are thereforelocated at the same height position of the associated carcass side walls14 a, 14 b. Hereinafter, it is only the fastening of a guide unit 18 ofa guide unit pair which is described, wherein the fastening of theoppositely lying other guide unit to the assigned carcass side wall 14a, 14 b is effected in the same manner.

The guide units 18 can be so-called standard guide units, which is tosay a modification of the guide units 18 for the purpose of thefastening to the assigned assembly interface 20 a, 20 b is notnecessary.

A respective guide unit 18 comprises a carcass rail 30 and at least onerunner rail 21 which is linearly movably guided on the carcass rail 20,wherein the carcass rail is fastened to the carcass side wall 14 a, 14 bat the assigned assembly interface 20 a, 20 b.

In the shown exemplary case, two runner rails 31 are provided, of whichonly one is shown, wherein one of the runner rails 31 represents adrawer rail which for its part is connected to the drawer via suitablecoupling means, and a middle rail (not shown) which is arranged betweenthe drawer rail and the carcass rail 30 and which is movably guidedrelative to these two rails. Such an arrangement is also denoted as afull pull-out.

The carcass rail 30 serves for fastening the guide units to the assignedcarcass side wall 14 a, 14 b at the assigned assembly interface 20 a, 20b, said carcass rail in the fastened state being connected to theassigned carcass side wall 14 a, 14 b in a stationary manner.

The carcass rail 30 comprises a carcass bracket 32 which comprises aguide section 33 (FIG. 5) which in the assembled state of the carcassrail 20 projects inwards from the inner side 24 of the assigned carcassside wall 14, 14 b. The middle rail is movably guided on the guidesection 33 via suitable guide means and the drawer rail is linearlymovably guided on this middle rail again via suitable guide means. Thecarcass bracket 32 further comprises an assembly section 34 which isshown in more detail for example in FIG. 3 and in FIG. 4 as well as inFIG. 5. The assembly section 34 is designed in a plate-like manner andbears with its outer surface on the assembly surface 25 of the assemblyinterface 20 a, 20 b. The assembly section 34 comprises a plurality ofassembly holes 36, so that suitable ones of the assembly holes 36 can bebrought into flush alignment with the fastening holes 22 of the assemblyinterface 20 a, in order to carry out the subsequent assembly procedure.

As is particularly shown in FIG. 3, the fastening holes 22 of theassembly interface 20 a, 20 b are arranged in several hole groups 35 a,35 b which each comprise several fastening holes 22 which are arrangedin a common height plane in the side wall depth direction 21, whereinthe hole groups 35 a, 35 b are arranged above one another in the sidewall height direction 19. In the shown example case, two hole groups 35a, 35 b which lie above one another in the side wall height direction 19are provided, of which a first hole group 35 a comprises several, forexample 6 fastening holes which are arranged in a flush manner behindone another in the side wall depth direction. The second hole group 35 bwhich is arranged offset to this in the side wall height direction 19and in the example lies deeper likewise consists of several fasteningholes for example three in number, which are arranged behind one anotherin the side wall depth direction. The multitude of fastening holes 22 inthe hole groups 35 a, 35 b, in the context of the assembly holes 36 onthe assembly section 34 of the carcass bracket 32 permits the carcassrail 30 to be able to be adjusted in the side wall height direction 19as well as in the side wall depth direction 21 and despite this theassembly holes 36 and the fastening holes can be aligned in a matchingmanner depending on the adjustment position.

As is particularly shown in FIG. 3, the channel-like deepening of theassembly interfaces 20 a, 20 b also forms a type of assembly aid onassembly on the carcass bracket 32, to the extent that the dimension ofthe channel-like deepening in the side wall height direction 19corresponds roughly to the height of the assembly section 34 andtherefore on assembly it is clearly evident that the assembly section 34of the carcass bracket 32 belongs in the channel-like deepening.

As is particularly shown in FIGS. 4, 5 and 8, after the aligning of theposition of the assembly section 34 on the assembly surface 25 of theassembly interface 20 a, 20 b and the associated alignment of thematching fastening holes 22 on the one hand and the assembly holes 36 onthe other hand, the carcass bracket 32 according to the first embodimentexample is screwed onto the inner side 24 of the associated carcass sidewall 14 a, 14 b via screw fastening means.

As is particularly shown in FIG. 8, the screw fastening means comprise afastening screw 37, in particular in the form of a self-cuttingfastening screw. Furthermore, a fastening sleeve 38 which usefullyconsists of plastic is counted as belonging to the screw fasteningmeans.

As is further shown in FIG. 8, the associated fastening hole 22 in thecarcass side wall 14 a, 14 b is arranged in a depression 39 which isformed by way of pressing out the material of the carcass side wall 14a, 14 b outwards from the inner side 24.

The fastening sleeve 38 comprises a disc-like sleeve head 40, onto whicha cylindrical base section 42 connects along a sleeve longitudinal axis41, said base section passing through the fastening hole 22. A fixationsection 43 whose diameter is larger than the diameter of the cylindricalbase section and also larger than the diameter of the fastening hole islocated at the free end of the fastening sleeve 38. The fixation section43 consist of two semicircular segments 44 which are separated from oneanother via a radially running longitudinal slot 45. The two segments 44are deformable in a manner such that the fastening sleeve 38 with thefixation section 43 and the segments 44 in front can be pressed throughthe fastening hole 22 amid the deformation of the segments 44, whereinthe segments 44 after the passage of the fastening hole can snap backagain into their initial position and ensure that the fastening sleeve38 can no longer slide out of the fastening hole 22 counter to theinsertion direction, since the segments 44 are supported on the outerside of the carcass side wall 14 a, 14 b. On pressing in the fasteningsleeve 38, the sleeve head 40 is positioned in the depression 39, bywhich means the sleeve head 40 does not project beyond the inner side ofthe carcass side wall 14 a, 14 b, thus beyond the assembly surface 25.

For fastening the carcass bracket, the associated fastening screw 37 isthen screwed through the central opening 46 in the fastening sleeve 38,wherein the diameter of the central opening 46 in the region of thesleeve head 40 is significantly smaller than the diameter of the screwshank 47, so that the fastening screw 37 with its thread cuts into thematerial of the sleeve head 40 and therefore clamps the assembly section34 onto the assembly surface 25.

As is particularly shown in FIG. 3, the carcass side walls 14 a, 14 beach comprise at least one opening 48 for leading through an electricallead, in particular in the form of an electricity cable. In the shownexample case, the openings 28, for example two in number, are arrangedbehind the ladder-like structure of the assembly interfaces 20 a, 20 bseen in the side wall depth direction 21 from the front side 26 of theassembly interfaces 20 a, 20 b. The openings 48 for example can have thefashion of an elongate hole.

As is particularly shown in FIG. 4 and also in FIG. 5, at least onedeepening 49 which is usefully recessed in the region of the embossings23 is formed on the carcass side walls 14 a, 14 b. The deepenings 40 canbe carried out for example by way of an embossing or punching procedure,which can be carried out after forming the embossings 23. The deepenings49 serve for receiving a light element 50 which is shown for example inthe form of an LED element. As is particularly shown in FIG. 7, the LEDelement is located in a receiving sleeve 51 which for its part isincorporated in an assembly hole 52 which is attached in the deepening49 and is mounted there. Usefully, the longitudinal axis 53 of thereceiving sleeve 51 is directed from the outside to the inside obliquelytowards the base 15, so that the light cone which is produced by the LEDelement is directed obliquely downwards and in particular is suitablefor illuminating the interior of the drawer.

As is shown in FIG. 6, it is possible for fastening holes 22 of theassembly interfaces 20 a, 20 b which are not used to be occupiedbeforehand by fastening sleeves 38.

As is particularly shown in FIG. 2, the carcass side walls 14 a, 14 band the base 15 are connected by way of fastening means 54. Thefastening means 54 are configured for the tool-free fastening of thecarcass side walls to the base.

In the shown example case, the carcass side walls 14 a, 14 b asmentioned are of a sheet metal and the base 15 of wood. With thiscombination, fastening means 54 which comprise claw elements 55 whichdig into the material of the base 15 are suitable.

As is further shown in FIG. 2, fastening webs 56 are formed on the loweredges of the carcass side walls 14 a, 14 b, said fastening webs beingable to be manufactured for example by way of an essentiallyright-angled edging away of the lower edge of the carcass side walls 14a, 14 b. Claw elements 55 are located on the upper side of the fasteningwebs 56, thus directed towards the interior 17, so that the base 15 isinserted and the claw elements can herein be driven into the lower sideof the base 15.

As already mentioned, transverse profiles 16 a, 16 b are provided as anupper termination of the furniture carcass 13 according to the firstembodiment example, said transverse profiles being able to consist forexample of wood material and being fastened to the carcass side walls 14a, 14 b by way of fastening profiles 57.

As is particularly shown in FIG. 1, the fastening profiles 57 can bedesigned in a manner such that a connection onto an adjacent furniturecarcass 13 irrespective of the type is also always possible via acoupling interface 58 which is provided for this. In the example case,the coupling interface comprises several, in particular two fasteningholes 59 (FIG. 3)

FIGS. 9 and 10 show a second embodiment example of the piece offurniture according to the invention. In contrast to the previouslydescribed first embodiment example, the carcass sidewalls 14 a, 14 b ofthe second embodiment example can be designed differently. Usefully, thecarcass side walls 14 a, 14 b likewise consist of sheet, in particularmetal sheet. The carcass side walls 14 a, 14 b of the second embodimentexample also each comprise at least one assembly interface 60. Theassembly interface 60 again comprises several, for example two fasteningholes 61, which are arranged behind one another in the side wall depthdirection 21. In contrast to the previously described first embodimentexample, the fastening holes 61 of the second embodiment example aredimensioned significantly larger and are in the form of window-likeopenings. The assembly interface 60 is again designed deepened in achannel-like manner, wherein preferably in the shown example case thetwo fastening holes 61 in the form of window-like openings are arrangedon the front and rear end of the channel-like deepening 62.

As with the first embodiment example, guide units 18 are fastened at theassembly interfaces of the second embodiment example. Here too, twoguide units 18 of a pair are fastened lying opposite one another andtogether serve for guiding a drawer.

In contrast to the previously described first embodiment example, arespective guide unit 18 is however designed differently. The carcassrails 63 of such a guide unit 18 comprise two assembly elements 64 a, 64b which are arranged behind one another in the rail length direction.The assembly elements correspond to the window-like fastening holes 61on the assembly interface 60.

The assembly elements 64 a, 64 b replace the assembly section 34 of thestandard carcass rail. The assembly elements 64 a, 64 b each comprise abase section 67 a, 67 b which is attached onto the guide section 66 ofthe carcass rail 63 in particular as one piece to this, and a plate-likeassembly section 68 a, 68 b which is aligned in the height direction ofthe guide unit 18, is connected to the base section 67 a, 67 b andprojects transversely from this. The outline of the assembly sections 68a, 68 b is smaller than the opening cross section of the assignedfastening hole 61, in a manner such that the assembly section 68 a, 68 bcan be stuck through the fastening hole 61 and is fastened to the edge69 which surrounds the fastening hole 61 and is formed by the carcassside wall 14 a, 14 b, by way of holding means. The holding meanscomprise a clamping tongue 70 which is preferably bent out of thematerial of the assembly section 68 a, 68 b counter to the insertdirection, by way of which tongue the assembly section 68 a, 68 b isfixedly clamped to the edge 69 of the fastening hole 61.
